​A man who was considered a family friend has been sentenced to 93 years in prison. In a plea deal, Mark Alan Gwaltney admitted to aggravated rape of a child, aggravated sexual battery and especially aggravated sexual exploitation of a minor. He was caught in October 2015 raping an infant on video just days after babysitting the 8 month old. Court records show the victim's sister accidentally found the videos when she asked to borrow his iPad. Gwaltney will have to serve 100% of the first 90 years of his sentence.
